More information about /SAPAPO/CDFT & MLR.EXE

I was checking the code of /SAPAPO/CDFT function and there is no documentation about the method it uses. I think it would be a sort of numerical method algorithm.

My customer is asking us for documentation regarding this function and also MLR.EXE and the method it uses (I think least squares). If there is any provider or documentation it would be good for us in order to provide it to our customers and encourage them to be confident with APO-DP.

Thank you in advance.

Hi Carlos,

The linear regression used in APO-DP univariate forecasting and causal analysis are based on the least squares method. With respect to MLR.exe, it's windows based (32 bit) legacy program that executes the statistical method. However, it is discontinued with SCM7.0 EHP1 and SAP native ABAP engine can execute the MLR within SAP. Please refer SAP note 1444688 https://service.sap.com/sap/support/notes/1444688 for details. Please note that SAP did not provide any documentation on MLR.exe.

You can find MLR related information in SAP help documentation at

Dear Rajesh,

Thank you for the information, however I just want to know who was the builder of this MLR.EXE (C++ program). As far as I know ILOG SA was the co-developer for APO Optimizers (SNP, PP/DS, ND, VSR, SEQ, CTM, MMP) but there is a lack of information for this .EXE.

It's nice to know that it will be replaced by ABAP code, however I remember a class where they told me why it was better using C++ instead of ABAP (for optimizers):

  • Faster programs
  • Data structures that are most suitable for optimization

There is also a doubt regarding the algorithm for /SAPAPO/CDFT function, where was it taken from?

Best regards,

Carlos Rodriguez

Hi Carlos,

You are correct. ILOG, France developed all these OR based planning algorithms for SAP. Since there is no database transactions and program translations are involved, we can expect better performance from C++ programs. SAP did not make any information available to public except the installation and configuration (RFC connections, etc). I am sure that they would have some documentation internally accessible only to SAP employees. Probably, it would be a good idea to approach SAP for information.

Regarding /SAPAPO/CDFT, I am not sure. It might support the new feature i.e. MLR forecasting using POS data. Please check the note https://service.sap.com/sap/support/notes/1617125 and ABAP correction attached to the note for details.

Thanks,
Rajesh

Thank you for the information Rajesh, however the notes you mention don't help me at this time, if you have information about what I am asking, I would be very pleased.
