Hello,

Could anyone tell me, plese, why

PurgeChar(peek(debit_date), SubField(peek(debit_date),'-',1))

returns '-8.5.24',

if the incoming string is '100000-08.05.2014'?

Thanks in advance

If I have figured out correctly your problem, i think a possible solution is:

Step1: index the '-' character with the index function

in your specified case index function in debit_date field, for '-' character returns 7

INDEX FUNCTION: index(debit_date,'-')

you have to use this value in the FINAL FUNCTION..

Step2

use the result of the first step to select only the string partyou need (in your case date part)

FINAL FUNCTION: mid(debit_date,index(debit_date,'-'))

This method solve the problem of the debit string lenght.

what exactly output you need?

Report Inappropriate Content · ‎2014-10-28

'-08.05.2014'

try like this

Subfield( Debit_Date,'-',2)

Because the function returns 100000 (1 and 0) as characters to exclude in the string -08.05.2014

SubField(peek(debit_date),'-',2)

MarcoWedel · ‎2014-10-28

forgot the leading '-':

'-'&SubField(peek(debit_date),'-',2)

MarcoWedel · ‎2014-10-28

Or simply

Right(peek(debit_date),11)

if the date format is always the same

Marco, thank you for response.

The problem is that rhe string is not always '100000-08.05.2014' it might be a longer string, containing debt and its start_date.... it might be '100000-08.05.2014-50000-25.04.2014', for example. and i need to evaluate the first subfield (this is the sum of debt to be fully or partly repaid) and leave teh rest part of the string unchanged.

How can i solve it?

The SubField(peek(debit_date),'-',2) solution should work for those field values as well:
