Payment release workflow

Hi Expert,

I need guidance regarding payment release workflow. I had created a workflow customizing settings.

At the time of creation of Invoice in FB60 the invoice is blocked with the payment block indicator "P".

While trying to release in FB13 the release option is grayed out.

I am not getting any event generated in the transaction SWEL.

i am not getting any information in SBWP in business workplace also.

Kindly guide me where I am going wrong.

Thanks

Regards,

Anamika
