Straggler is a record, by which the value of a split characteristic is 2 years older than the year, in which the loading or activation was performed. The analysis indicates how many load or activation requests contain straggler records.

Example:

We have the DSO object ZDSO1 with the split characteristic 0CALDAY. The straggler analysis checks the activation request ODSR_XYZ, which was executed on the 13.04.2018. The activation request ODSR_XYZ contains a record with the value of 0CALDAY 20160113.

Extract year of the activation request is the 13.04.2018 → 2018

Extract year of 0CALDAY is the 20160113 → 2016

Default parameter, based on which a record is identified as a straggler, has the value 2 years.

This record is a straggler because:

year value of 0CALDAY + checking/default parameter <= year value of the request load or activation

2016 + 2 = 2018 <= 2018

The parameter, based on which is checked whether a record is a straggler, can be set in the expert settings (transaction /DVD/RL_SETT_EXPERT) on a satellite system.

Tool name = HMBW

Parameter tech. name = HM_BW_WRITER_STRUG_RETEN

Other parameters

HM_BW_WRITER_LOG_NOT_MATCH

The Straggler analysis is checking year values of the split characteristics. In the case the year value contains a year which doesn't correspond to data partition of Data distribution analysis, then if we switch this parameter on, an error log will be added to the application log. This feature is disabled by default, but can be enabled using the parameter HM_BW_WRITER_LOG_NOT_MATCH of the expert settings. Set the parameter to X to switch functionality ON.
