Goods Issue reversal TU

Hi All,

We assign deliveries to TU and do Goods Issue at TU level. Now the problem is when they want to do Goods Issue reversal for one particular order they were not able to do it . SAP says you have to do reversal for all the deliveries. I could see that only one internal warehouse document created  with process type 2010 for all the deliveries. Document has item number 1 2 3 and so on..When we do goods Issue in delivery screen individually seperate warehouse document is created .

Any solution to do goods reverse !

THanks,

Srini
