No Change Document in outbound queue for customer status in table VBUP

Hello all,

we face the following issue. A customer status (UVP04), changed by a customer program, is not written in the outbound queue (lbwq) to transfer it in the business warehouse.

I checked several Function modules (VERKBELG_WRITE_DOCUMENT, MCEX_UPDATE_CALL_11.....) without success.

Any help would be appreciated.
