I have an issue which is little bit strange and I think it might be a technical issue rather than functional. But I decided to consult you (experts) at first perhaps I am mistaken an it is functional issue.
When my colleague go to MM01 to extend some materials like 800025841 for instance system returns a message (Enter a material type).
BUT when I did same process on my PC I did not receive that Error Message and the system continued normally, then I let my colleague to access SAP MM01 from my PC, it worked with him. To give it sufficient investigation I logged on system from my colleagues PC I received same error.
conclusion : that the error occur from one PC but if to logon from another PC, no problem !!!
Thanks in advance;
