Runtime error CONVT_NO_NUMBER has occurred

Question

Dear experts,
I am using BAPI -- 'HR_MAINTAIN_MASTERDATA' to maintain infotype 8(Basic pay).
I debugged the code. The data is coming in IT (that is of type PPROP) from my text file. But it gives runtime error in the FM saying --
"Runtime error CONVT_NO_NUMBER has occurred"
Please guide,
Sumit.

hi,
I checked in ST22. It says unable to interpret 4B as a number. Now I went to transaction PA30 and checked it's possible values. There were only 2- 8A and 8B. so I changed it to 8B. But still gives same error, as unable to interpret 8B as  a number.
This is my int table while debugging--
line infty(c4)  fname(c132)   fval(c255)   seqnr(n2)
1     0008     P0008-PERNR     40083005     00

12     0008     P0008-WAERS     INR     00
13     0008     P0008-LGA01     INR     00
14     0008     P0008-BET01     4000     00
15     0008     P0008-LGA02     4657     00
if fval is of c255, why doen it interpret it's fields as a number?
