Accrual Object Table for Account Assignments

I have appended the structure ACESOBJ_ASSGMT_ATTRIBUTES with a field SGTXT and LIFNR so that I can use those fields in the accrual object in the Account Assignments.

Now I would extract the accrual objects to an external system but I cannot find the table in which those information would be stored.

The only Table that I am aware of in the accrual management is "ACAC_OBJECTS" but there nothing useful is stored.

Appreciate your help.
