Dear All,
I have read the previous post:@HspNumToString - error in Calc Manager Script, but I am on EPBCS now.

I have ticked “create from members”, and my rule is as follows:
SET UPDATECALC OFF;
FIX("No Department",@Relative("Type",0),Forecast,FY23,@Relative("CostCentre",0),"Jan":"Dec",@Relative("Employee Type",0),"Salary","BaseData")
"Working"(
IF(@ISMBR(@MEMBER(@CONCATENATE("HSP_ID_",@HspNumToString("StartMonth"->"BegBalance"))):Dec)) @xwrite("Salary"->"BegBalance"*"TP_Days"->"No Department"->"No CostCentre"->"No_Type"->"No_ET"/"TP_Days"->"No Department"->"No CostCentre"->"No_Type"->"No_ET"->"YearTotal",@loopback,"Working");
ENDIF
)
ENDFIX
It threw the following error when I launched the business rule(it still get validated):
Cannot calculate. Essbase Error(0): Error executing formula for [Working, at or after line: [" @xwrite("Salary"->"BegBalance"*"TP_Days"->"No Department"->"No CostCentre"->"No_Type"->"No_ET"/"TP_Days"->"No Department"->"No CostCentre"->"No_Type"->"No_ET"->"YearTotal",@loopback,"Working");"]] (line 9): invalid argument in function [@_BPROC]
What is the error code “@_BPOC”?
Can someone please help with this? Your help is much appreciated:)
