Eror log

I got this error message while running simulation:

Setup of Projection Factor

Invalid parameters for an operation

Operation RTE= SPRJF

Calculation rule ZNN0***** RTE= SPRJF ADDWTI/401

Find below the rule:

RTE= SPRJFADDWTI/401

THE RULE CAN BE CHANGED TO SUITE THE PROJECTION LOGIC

RTE=FX T RTE/30 RTE-1 RTE< TPRJFRTE-30 NEXTR

RTE>FZ T RTE/-30 RTE>0 ROUNDBK100ADDWTI/401RTE= FPRJF

Any idea on what could be causing this error message?
