create AuC settlement rule and settle to assets

Hi Experts,

we have a requirement to automate the creation of AuC settlement rule and distribute it to asset using distribution rule.

We failed using BDC for AIAB transaction as BDC does not work for ALV Grid List.

Now we are using the FMs K_SETTLEMENT_RULE_FILL, K_SETTLEMENT_RULE_SAVE and ANEK_UPDATE_BUREG in a sequnce to create the AuC settlement rule and save that rule.

Problem :

The FM K_SETTLEMENT_RULE_SAVE fails to update the DB tables 'COBRB' because some how in the custom development the update flag 'UFLAG' is setting as 'U' (Update), inspite of the fact that there is no corresponding entry already present in the COBRB table to get updated.

We can not change this flag value explicitly passing through the importing parameters of the FM K_SETTLEMENT_RULE_SAVE.

Please let us know the solution, how we can achieve this Rule creation through our custom development.

Regards,

Dixit Miglani
