Process chain - not running as a background process

Hi experts!

We created a program to upload 5 CSV files. When the user uploads a CSV file, this Z programm triggers a background process to start the process chain.

The code of the function in the Z-program is the following:

call function 'RSPC_API_CHAIN_START'

exporting

i_chain = vl_pchain

i_synchronous = 'X'

i_dont_wait = ' '

i_poll = ' '

importing

e_logid = vl_logid

exceptions

failed = 1

others = 2.

In development we upload the CSV files and it works ok (the process chain finishes in green).

• When we transported to Testing, the process chain remains in yellow, we fon't know why.
• But, when we enter via rsa1 --> process chain, and we manually run it, it finished ok (in green).

How can we fix this? We need to upload the CSV file, and the process chain that is executed in a background process should finish in green.

Thanks in advance.
