if first 2 letters in column 'H' items codes contains
BT then it will show BTS and likewise if
MW then Minilink / Access Link
BS then BSC
MS then MSC
IN then IN
TE then Transmission
TS then Transmission
NM then OSS
SE then Services
AN then GSM antenna
NL then NLD-OFC
MP then MPBN
VA then VAS
TW then Civil & Infra
ST then Civil & Infra

SH then Civil & Infra
PS then Civil & Infra
