Validation in Project Definition No Range
I am creating a validation of project definition number range specific for a project profile but not get sucess.
Scenario is like this..i have a project profile Z000001 for which there is a number range of project code 1000 to 1999

Prerequisite :- PROJ-PROFL = 'Z000001'
Check :- ( ( PROJ-PSPID :4-7: >= '1813' ) AND ( PROJ-PSPID :4-7: < '2000' ) )
Project Code logic is XX/XXXX , ex PL/1814
