It has been a long time SAP release this program to cover MX DIOT report for Mexico.

However I not feel very confident it is working or fixed now. (2017)

Does someone have documentation for this old program?

There is no documentation on SAP Notes. (no clear documentation)


After some debugging we could find tables MXTVO and T007k should be filled in specific order that are not really clear.

We are pretty sure we have setup RFUMSV25 program correctly and our tax codes (origin and target) has been customized correctly (even the table BSET is working properly)

How to fill tables MXTVO and T007k tables?

It is another hide table to be filled?

Why the output list is so different from the txt file output?

(there are missing vendors)

After guessing we should made the following entries on MXTVO

3 - N03 (For Services)

85 - N85 (General Others)

And is specific order we supposed...

MX N03 S0 VST 15 (origyn)
MX N03 S1 VST 16 (origyn)

MX N03 SE VST 17 (origyn)

MX N03 T0 VST 18 (target)

MX N03 T1 VST 19 (target)

MX N03 TE VST 20 (target)

MX N85 V0 VST 21 (origyn)

MX N85 V1 VST 22 (origyn)

MX N85 VE VST 23 (origyn)

MX N85 W0 VST 24 (target)
MX N85 W1 VST 25 (target)
MX N85 WE VST 26 (target)

After some testing most of the documents (invoice with taxes already cleared) appear on the output report but not in the txt file!

Many thanks for your help

After some investigation there absolutely no SAP documentation regarding this program

However the best approach to fill tables MXTVO and T007K until now is the following:


a) You should post the deferral tax program (check whether BSET table is working properly)

b) Only target tax codes are relevant

c) The hide table MXTVO must be filled with separate categorization (others N85, services N03, and so on).

d) SAP expect you create new set of tax code for each category, others, services, etc due the system is not able to classificate

e) SAP expect you create new set of tax code for national and imports (even though the country of the vendor is on master data, the system is not able to determine the orygin; this cause make the tax code list a big issue (consider using the SAP enjoy transaction to clean the list)

f) Go to SAT web page and download the DIOT application, there is a manual about the column number 2014 is the newest.

g) Classificate the base amount tax target accounts according the column number, using now the T007K base tax amount table (there is also an another hide table T007L for tax amounts, but is not sure if apply)

h) For MX localization there is a big issue for date selection, it seems be retrieve by invoice posting date instead payment posting date. More investigation is required.

i) It seems work properly work with MX withholding tax code, but be sure to be selected on the selection parameters

May I suggest you to create your own custom program, since no SAP proper documentation is available.
