SAP Note 12257 - SAPLPD,SAPfax: WinFax displays popup for fax number.

Symptom:

Facsimile transmission from R/3 via Windows PC with SAPLPD, SAPFAX.DLL, WinFax PRO: when a facsimile message for transmission arrives in SAPLPD on the PC, WinFax PRO opens a pop-up window querying the fax number of the recipient. The field does not contain a suggested value.
Depending on the versions of the programs involved (SAPlpd, SAPfax), the system reacts differently:

a) Pressing the "Send" button (without entering a fax number!) sends the fax to the addressee specified in R/3 (or taken from the address dataset).

b) An error message is shown by SAPLPD: "SAPFAX.DLL didn't work" (although there has been the message "SAPFAX.DLL ok." when starting SAPLPD). Pressing the "Send" button without entering a fax number does not cause the fax number to be copied from R/3. It has to be filled in manually.

Cause and prerequisites

a) Error in passing on the fax number (using a DDE command) from SAPLPD (through SAPFAX.DLL) to WinFax PRO.

b) Error in SAPLPD when trying to call SAPFAX.DLL.

Solution
Fixed with the new SAPLPD ver. 2.30 and SAPFAX.DLL ver. 1.07 Until these programs are officially released and shipped, beta versions can be obtained from SAP via FTP. Please refer to note 16420.
