Why the ABAP Development is server down after using access Key?

I have use access key to change the field length of a data element from 12 to 16. The table is a custom table with naming convention ZVENDOR and the field name is 'REFERENCE'.As this field is currently 12 characters long, to accommodate 16 characters, I change it to 16. How ever it asked me about the access key while I tried to change the field length.After changing the length of data element, I have activated it without deleting the TMG(Table Maintenance Generator). After few time the development server got down and i am unable to use the development server.While contacted the BASIS team, they said that it is because of the use of access key by abaper.

Please help by providing better solutions for the below questions.

1.How to bring the development server live again.

2.After the development server is live again, should I proceed for another attempt to change the length of the data element with the help of the Access Key,like I have done before.

    What is the Data Element that the field ZVENDOR-REFERENCE is referring to ?

    As it asked for SSCR Key,I assume it is a Standard Data Element.Seems you changed the length of a Standard Data Element and Dev Server down "could be" the repercussion of that activity.Btw,did you get to check ST22 dumps,if any ?

    Instead of changing the standard data element,you should have created/used a Z data element with the desired length.

    • To add to this comment - go to the table SE11, Display it, click on append structure. But yes your system would go down with all the errors it was generated when the SAP programs were trying to access the data element that had been changed.

    Assuming by "down" you mean no-one can log on, it is your Basis team's job to get the server running again. I guess they may try a restore from backup. As a developer, you can't do anything to fix the server yourself when it is down.

    While the server is down, I suggest you fill the time really getting a grip on what domains are in the context of the data dictionary, and gain an understanding why changing the length of a SAP supplied domain is a staggeringly bad idea and should really be attempted.
