How to restrict write access to PLP register using Data cell access security.
Hi OS Community,
We have custom business rule to manage Data cell access security (Slice security). We have created new row category(DHRStat_Fcst)select group and it should have Read access only to PLP register but issue is it also have write access to add or make changes to register (screenshot below highlight in yellow) which we are trying to retrict through BR.

Custom BR code:

Line 253-259 is it is for data cell read access for PLP register
Line 263- 264 is the code for write access for PLP register and we try to restrict by category, but it is still not working.
If Not itemAccess.Category = "DHRStat_Fcst" AndAlso itemAccess.MemberFilters.Scenario.IndexOf(wfscenarioname) > -1 AndAlso brapi.Security.Authorization.IsUserInGroup(si, groupID) Then
dashSet = "3b2b1w_RegisterMaint_PLP"
End If
Data access:

I need help with the BR code change to restrict the write access to the particular Data cell category .Let me know if you need any more details.
Appreciate your help!!
