Validating problem

Former Member — Tue, 30 Jan 2007 20:21:52 GMT

I developed a code a to validate the serial number (SERNR) ...... The serial number entered is 9 characters... But at the runtime...it is preceeded by 9 zeros making valid entered number invalid.How can i remove those extra zeroes..

You can do this a number of ways. First you could simply SHIFT it.

SHIFT SERNR left deleting leading '0'.

You may also use NO-ZERO with WRITE statement.

NO-ZERO

If a field contains only zeros, these are replaced by blanks. For type C and N fields, leading zeros are replaced automatically.

WRITE: '000123',

/ '000123' NO-ZERO.

Output:

000123

123

If i understand you correctly, you have SERNR as a user-input option, and at runtime, it is left-padded with zeroes. This means that your input parameter is of type N, whose default-value is filled with zeroes.

One way to overcome this would be to change the definition of the parameter to type I or type C, depending upon whether you expect characters or not.

Further, there are conversion-modules to convert a user-input value to the internal format. Check SE37 with the name CONVERALPHAINPUT - you could use either the generic FM, or a specific one for your field.
