for sap specific data fields
for example
if the field html is as follows
we can access the field using the following selector
SapDataField('wnd0/usr/subSUB0:SAPLMEGUI:0019/subSUB3:SAPLMEVIEWS:1100/subSUB2:SAPLMEVIEWS:1200/subSUB1:SAPLMEGUI:1301/subSUB2:SAPLMEGUI:3303/tabsREQ_ITEM_DETAIL/tabpTABREQDT1/ssubTABSTRIPCONTROL1SUB:SAPLMEGUI:1328/subSUB0:SAPLMLSP:0400/tblSAPLMLSPTC_VIEW/ctxtESLL-SRVPOS2,0')
it will automatically replace unsafe characters with escaped representation and build the selector from it that can be used to access the field in the browser
when the input field is nested within an element with lsdata attribute
this will match the first input field within the element with matching lsdata
even if the input field itself does not have lsdata attribute
