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

Supported changes for specific objects

Glue Table

Glue object	Scenario	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	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	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
Variant	Change the select option values

Extractor 2.0 objects

Glue object	Scenario	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.
Process	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:

Change the Glue object on the source system.
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
Release this transport through standard SAP procedure
Import this transport through standard SAP procedure
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:

Delete the Glue object on the source system.
Create and import a deletion transport for this object.
Create a newly changed Glue object on the source system.
Transport newly changed Glue object through a standard transport.
