Customer ATP Add-on throwing an error this is not an icharge issue

Product version:          

I charge 11.0.0.16

Problem statement:

Customer has informed that recently STS has reported an issue that gets thrown whenever they "Calculate ATP" on a Sales Order. This is a custom "Color Matrix" add-on that was built for them. The error that is raised
"Invalid Column Name "ClosingBalancetemp1" they have checked the stored procedures and there is a field with that name  declared.

Proposed Solution/Workaround:

We provided the stored procedure 'sp_CTX_GetATPDate_S2S' which was provided by iCharge development team. After executing the stored procedure, iCharge Addon was able to be connected and worked fine.
