default value for subitem with BDC

[jerry_wen]

I have a record with FS item BDC value 1B00:

the selection S-BC-TT-02 is looks like this:

As you can see there are multiple values have been define in the selection, after I released the data, 915 was populated in ACDOCU table for field Subitem, I would like to know what is the logic the system decided to use 915 as the default value when release the data instead of the other value from selection?

Hi,

Check S/4HANA for Group Reporting > Master Data > Define Default Values for Subassignments > Subitem and you will find out the default value configured in case it is not found in the selection or is empty.

Regards.

Thanks for explanation, if the transaction type value in S/4 is "900" for this record, which is one of the value under selection "S-BC-TT-02", the subitem value in GR will be populated with value "900", the selection expression in the above selection "S-BC-TT-02" screen shot contain all the possible values from ACDOCA, right?

If the subitem is blank in the source data, then the BDC will default the Default transaction type.

If you have a business requirment to error out these records, change the Break Type from 2 to 3.
