Hi,
I understand that at the time of changing the cost center outbound IDOC should trigger automatically!
If this is the case you have to check the BADI:
| BADI_COOM_CI_CSLA_IDOC | Create COAMAS IDoc - Insert Customer-Defined Fields |
| COOM_CI_CSKB_IDOC | Create COELEM IDoc - Insert Customer Fields |
| COOM_CI_CSKS_IDOC | Create COSMAS-IDoc - Insert Customer Fields |
:
| Let me know if you are looking in other way! |
