Hi All,

Ia m working on a scenario where i need to submit a record for approval through a javascript button. I have tried submitting it for approval as a partner user but i always get an error message when i trigger it from the custom button. I thought of using process builder but that will again affect the order of execution as there are a couple of workflows and triggers running and this might mess it up.
I tried submitting the record through anonymous window and through batch and it got successfully submitted. Based on my understanding i am thinking that it is an issue with the user submitting it and scheduling is the only option. Any workarounds/suggestions will be of much help to me.
Below is the error message and the code i have worked on :
First error: Process failed. First exception on row 0; first error: NO_APPLICABLE_PROCESS, No applicable approval process was found.: []

//below is the code which i have altered so submit approval request from partner portal
