Char fields left filled with zeros problem

[Nobody/Anonymous]

Hello,

I have this problem: when calling a RFC using tables and putting numeric chars only in char fields, they get left filled with zeros till de width of the field, i.e if in python a do 1, i get in sap 001 in 3 char length fields,

I'im using pysaprfc and SAP 4.6B

Any ideas?

Thanks.

I think this is the code in pysap.py which is doing the conversion  (over line 200), but i don't know the reason why is doing it?

elif v.isdigit():
                try:
                    v1=int(v)
                    if v1<=sys.maxint: v=v1
                except ValueError:
                    self.int_value=v.ljust(self._length_)
                else:
                    if isinstance(v,int):
                        self.int_value='%0*d' % (self._length_,v)
                    else:
                        self.int_value=v.ljust(self._length_)

Any help from the author?

Thanks

The purpose of this code was to automatically format string containing numbers to ABAP format for numerical strings (numc) - right aligned with leading zeroes. SAP uses this quite offten to format  fields like customer or material numbers which can be both alphanumerical (left aligned) and digits-only (leading zeroes) and I wanted the string  to be easly compatible with values as store in database.
Latter I changed my mind - this kind of under-the-hood formating may lead to errors - and current CVS version doesn't use it anymore.

Thank you Klavdij for your quick anwser, so I think I can comment previous lines without hurt (I will test)because they are at the part of the code which treat with the STRING data type.

A question thought, Is it safe to use the code from CVS right now?

Thanks.

Code in CVS is in "pre-release" state and should be fairly safe. I'm using it in couple of my projects and it seems rather stable.

Hello,
I have a similar problem using pysap. Example executed in idle:

# get the interface
>>> r_func=zhl_conn.get_interface('Y_4Q4_REQUEST_LICENCE_MESEQUI')
>>> r_func.keys()
['RETURN_TAB', 'GRUPPENID', 'LIZSCHL']
# assigne values to the import keys
>>> r_func['GRUPPENID']='1514100'
>>> r_func['LIZSCHL']='PCDELUN70099103AVS'
# call the function
>>> rc=r_func()
# print the return_tab
>>> for i in r_func['RETURN_TAB']:
    print i
   
tdformat = '1 E:'
tdline = '00000000. GruppenID nicht vorhanden'
>>>
# Expected:
tdformat = '0 M:'
tdline = 'PCDELUN70099103AVS' Lizenz OK

Reason is that the lenght of r_func['GRUPPENID'] is doubled (type of GRUPPENID in SAP is CHAR length 8)AND the value then is filled with leading zeros. The left part of the value is then sent to SAP
>>> r_func['GRUPPENID']
'0000000001514100'
>>>

What happens ?

Thanks in advance
