Tcode Analysis?

[KatiNonhebel]

This may be a rookie question, but how do you find out the purpose of a custom tcode?

Background: Global company, very poor documentation processes, dog eat dog place with 0 mentorship or development.

Started a new project in which the foreign country R/3 environment has hundreds of custom tcodes but with no documentation. I have to figure what the custom tcode does as well as if it can be replaced by standard tcodes.

Example: One that has analyzed already by another co-worker: "Creates outbound file to send invoices from region. Along with equipment details from table X. Uses data from tables X,X. Generates file at outbound directory with name X. Sends serial number, customer, invoice date, and company code."

All of this found just by being supplied Tcode.

I'm not sure at all how to find this out. I've gone into SE93, but that only gives me the program.

Excuse my ignorance. Just trying to learn and figure this out.

Thank you for visiting SAP Community to get answers to your questions. Since you're asking a question here for the first time, I recommend that you familiarize yourself with https://community.sap.com/resources/questions-and-answers(if you haven't already), as it provides tips for preparing questions that draw responses from our members. For example, you can outline what steps you took to find answers (and why they weren't helpful), share screenshots of what you've seen/done, and use a more descriptive subject line. The more details you provide, the more likely it is that members will be able to assist you.

Should you wish, you can revise your question by selecting Actions, then Edit (although once someone answers your question, you'll lose the ability to edit the question -- but if that happens, you can leave more details in a comment).

Finally, if you're hoping to connect with readers, please consider adding a picture to your profile. Here's how you do it:https://www.youtube.com/watch?v=F5JdUbyjfMA&list=PLpQebylHrdh5s3gwy-h6RtymfDpoz3vDS. By personalizing your profile with a photo of you, you encourage readers to respond.

Hi juanmaddox

Get functional inputs from functional guys based on that check the code or debugging only can help. by query below check and bucket the z developments by objects and proceed one by one and also as mentioned in comment do follow the links on Question and Answer session
