I had not seen this post previously as I don't often visit this site, not being familiar with Payroll for DASH, but here are a few comments on your pcr.
You mention that your requirement is "to replace wagetype /370 with infotype 3253 field value", but the first operation you use in your pcr, for ESG * and WT /370 is ADDWT *. Therefore, WT /370 will end up in the Output Table unchanged.
You use operation VARGGYYGOS, presumably to make a decision on the "KSA localization", but as mentioned by Joerg, you probably need a Custom Operation (or an Include) to be able to read Infotype 3253. Then again, even if it would read field YYGOS of PA3253, the only return value you have supplied is **, meaning that no matter what KSA localisation value you add (again) the RTE, NUM and AMT of WT /370 into the Output Table as WT /370.
Assuming that your ABAP programmer has created a Custom Payroll Operation to read table PA3253 (call it Operation T3253), that YYGOS the IT3253 numerical field for "KSA localization", that one of the values of KSA localisation would be 99, and that you want to replace the Amount of WT /370 by 99 in such cases, then your pcr would look like this:
ESG * WT /370
T3253
VARGGYYGOS
**
ADDWT *
99
AMT= 99
ADDWT *
If you have found a way to meet your requirements, please post it as it may help others.
