Hi Experts,
We have an issue regarding General Ledger Account to be posted manually (FB01,FB50...).
For this posting the busines required only one Cost object (WBS or IO or cost center) is needed.
The problem is that I can not define a Field status group who require only one assignement, either WBS or IO or COPA.
Thus all General Ledger Account is alraedy created as Cost Element.
How can I create this validation rule ?
Thanks for help
