I found a 'Z' transaction calling a program not in the customer space. This program "seems" to be something developed by the customer, meaning its name is "AQZZZFI_ABC=====ZPYORD========", where "ABC" is the name of the company, and the creator of the program is one of the consultants there.
What could this program be doing outside of customer namespace? Is it auto-generated?
And if so, what framework generated it, and how can i get to the "real" development object?
Note: this program uses a logical database called "__S".
Programs prefixed with AQ are usually generated by SAP Query or the Quick Viewer.
