I guess all of us often had to work with files in ABAP usign some of available FM like 'GUI_UPLOAD', 'GUI_DOWNLOAD' etc. When doing so sometimes there is a need to display in ALV the filename with or without extension . There are plenty of FM that helps to do so but the have one disadvantage -> they base on 3 digit extension and sometimes they have limited path size.

But where stadard SAP cannot help you, then you have to helpyourself with ABAP. There is a really simple way to split filename/extension without any restrictions known from standard FM. Here is a code for a method, but you can use it also to create form or FM.

You've seen many times that in standard SAP transactions the dates can be presented in days, weeks and months although in database it's saved as normal DATS type. For sure in same table you can find the field called "External date type" which is used to convert standard date to external one. If you're designing a program in which you want to use same functionallity then FM 'PERIOD_AND_DATE_CONVERT_OUTPUT' and 'PERIOD_AND_DATE_CONVERT_INPUT' comes with a help.
