I was tying to implement the UI masking in my current system. It was working earlier after completing the configuration in SDMSK and SRALMANAGER. But now its does not seems to work and it always replaces the whole value with asterix. Upon further debug I found that in program SDYNPDMSK form DMSK_DYNPRO the call to C-program AB_GET_C_PARMS does not return the P5 (Rule Name) and P6 (Rule Mask) parameters. Can you please let me know what can be the probable root cause?
