How to split one record to multiple records?

Hi,
I have one tab delimited file which is having multiple store_ids in first column seprated by pipe.I want to split the file on the basis of store_id(separating 1st record in to 2 records ).
I tried some more options like below with using split,awk etc ,But not able to get proper output. can somebody please help here?

Code:

awk 'FS = "\t";{n=split($2,s,"|");for (i=1;i<=n;i++) {$2=s[i];print}}'

Code:

Input:

You were almost there. A small adaption to your code snippet yields the desired result:

Code:

awk '{n=split($1,s,"|");for (i=1;i<=n;i++) {if (s[i]) {$1=s[i];print }}}' OFS="\t" file
store_id    Age_21_25    Age_26_35    Age_36_45    Age_46_55    Age_56_65
