Glue Transport Management enables you also to change Glue objects on the target system. 

Supported changes for specific objects

Glue Table

Glue object		Scenario	Status	Notes
Table		Append fields to a Glue table		Columns are appended (added to the end of the table). If applied, Datavard Glue also adjusts the extractor automatically without any need to transport it. If a field was added only to an external storage table, the source field is empty. If a field was added to the SAP source table, it's mapped to a new field in the Glue table.
		Recreate a table structure		If you deactivate a table or add fields to the middle of the table structure and then activate and transport it to another system, you will receive an error. This error occurs, as adding fields to the middle of the structure isn't valid ALTER TABLE operation.  To recreate a table structure, delete the original table from the target system using a deletion transport and then import the modified table using a standard transport mechanism.
		Remove fields		Removing a field from a Glue table requires deactivation of the table. This means that you must follow the same procedure as described above.
		Modify File storage options		Modification of File storage options is possible except for changing the Container name parameter. To modify it, delete the original table from the target system using a deletion transport and then import the table with the modified container name using a standard transport mechanism.
		Change description		Change of table description is allowed. To change the description goto edit mode, change the description to desired one and activate table.

Glue Table created from external table

Glue object		Scenario	Status	Notes
Table		Append fields to a Glue table		Appending fields to a table created from external is not supported.
		Recreate a table structure		Altering a table created from external is not supported.
		Remove fields		Removing fields from a table created from external is not supported.
		Change description		Changing table description is not supported.

Extractor 1.0 objects

Glue object		Scenario	Status	Notes
Extractor		Add routines
		Add selection fields
		Add source fields
		Change Skip initial Full load		The value of Skip initial Full load flag will stay unchanged on the target system
Variant		Change package size
		Change the select option values

Extractor 2.0 objects

Glue object	Scenario	Status	Notes
Fetcher	Change selection fields		Selection fields are changed accordingly.
	RDE flag		Check/uncheck the "Read deleted entries" flag in Fetcher is changed accordingly.
	Change source object		Change source object to fetch data from e.g. SAP Table. This change will affect objects using the fetcher.
	Change delta type		Delta type is changed.
	Change load type		Load type is changed.
Consumer	Change enable merge		Enable merge is checked.
Process	Change start/end routine		Start/end routine is changed.
	Add routines
Queue	Change description		The description is changed.
	Change structure		The structure is changed.
	Change list of subscribers		The list of Active queue subscribers will stay unchanged on the target system.

Depending on the changes you performed on the source object, you should either use a standard transport or a deletion transport to transport the updated object to the target system.

• If you perform changes on the Glue object with a green status in the table below, you should use the standard transport for updating the object on the target system.
  In this case, proceed as described in the section Transport object to a target system.

In this case, you alter a Glue object in a way that is marked red in the chapter Supported changes and transport it with standard transport, the transport of this Glue object will fail.

• If you perform changes on the object with a red status in the chapter Supported changes, you have two options on how to transport the changed object to another system.

  We recommend using the first option, as you may transport changes from a source system to a target system without deleting the Glue object on the source system. During this option, delete the Glue object on the target system first and then import the changed Glue object from the source to the target system.

The first option consists of these steps:

1. Change the Glue object on the source system.

2. Create both deletion and standard transport for the changed object (this step will save user the need to use two separate transports) in both cases use the same Request Number when collecting changed object
3. Release this transport through standard SAP procedure
4. Import this transport through standard SAP procedure
5. Import this transport through Glue TMS (/DVD/GLTR)

Glue TMS will delete the changed object and create it with made changes with one transport. 

The second option consists of these steps:

1. Delete the Glue object on the source system.

2. Create and import a deletion transport for this object.

3. Create a newly changed Glue object on the source system.

4. Transport newly changed Glue object through a standard transport.
