Project definition and WBS validation (coding mask)
I need to have a validation coding mask when WBS under project definition must be same with project definition.
For example :
Project Definition : ABCD3PLH
WBS level 1 : ABCD3PLH1
WBS level 2 : ABCD3PLH2
WBS level 3 : ABCD3PLH3
I need validation to validate the first 4 character which ABCD.
What should i do in Validation (OPSI). Should i maintain in PRoject definition or WBS element ?
