Settings for Automatic MB1A(261 Prod Ord) immediately after TO is confirmed

Hi,

We have a scenario where system is set up such that as soon as users confirm Transfer Orders using LT12 - system does IMMEDIATE AUTOMATIC posting of MB1A - Goods issue - 261 movement type against Production Order.

We want to make some changes in to that.

Question is : Where are those settings for automatic MB1A after TO confirmation? Is it any Configuration? or BADI/BAPI/User exits are to be checked?

If someone can help us how to achieve automatic MB1A and setting of the same - we can change it.

Best regards,

Ravi Davda
