How to generate data in BPS via function, not having any reference data?

Question

<b>Hi everybody,
My approach was to use FM 'API_SEMBPS_SETDATA' but the modified values neighter appear in the layout nor were saved to the infocube after launching 'API_SEMBPS_POST'.</b>
<a href="http://help.sap.com/saphelp_nw04/helpdata/en/2e/260a8563b111d4b2ea0050dadfb23f/content.htm">Application Programming Interface (API)</a>
<b>What do I have to take into consideration?
Is there an other way to generate data in BPS?</b>
Thanks in advance,
Zeljko
Here my findings from debugging it:
In Step 1 FM reads data from planning level/layout correctly:
Line     ROW     COL     VALUE     INPUT
1     0001     0001     11     1
2     0002     0001     0     1
3     0003     0001     11     1
4     0004     0001     11     1
5     0005     0001     11     1
6     0006     0001     0     1
(Input = 1 indicates that Input is allowed in this cell)
In Step 2 FM modifies the values in all lines to 1:
Line     ROW     COL     VALUE     INPUT
1     0001     0001     1     1
2     0002     0001     1     1
3     0003     0001     1     1
4     0004     0001     1     1
5     0005     0001     1     1
6     0006     0001     1     1
Finally the modification is imported to FM 'API_SEMBPS_SETDATA'.

Hi Vlad,
I tried both alternatives:
1. Write data in buffer only, not in database
2. Write data in buffer and then writes from buffer to database
How can I check or see the data in the buffer? I tried the following: After executing the FM I opened the layout but the numbers are still the same.
