I have to derive an output as shown in the 'desired output' table based on a 'source table' using the logic given below. I got partially correct result, but there are few issues. Can the experts help please?

Source table has the id, ph, name & dept. The output table should have the ids for the combination of name & dept in ph 1 & 2. I see that the result is incorrect when same name is in multiple dept. It just counts the name in all ph & duplicate the result for dept.

For example, trtr should have 3 rows in the output with different ids. But all ids of trtr are duplicated against depts c, l & a. Cells with incorrect output are marked in pink.

Thanks, @JamesCanale. It works perfectly. (y) Thanks to you too, @Fluff. Unfortunately, I don´t have the PIVOTBY.

However, I would like to know what is wrong in the formula that I used. Can the experts help to fix the formula I used please?

I don't have pivotby either - I was amazed at the conciseness of Fluffs.

I can barely understand my solution - taking apart another one is really hard.

You are only filtering on name & ph, but you need to filter on name, dept & ph

Thanks, @Fluff. You are correct. I´m struggling to add dept in the filter. It is giving incorrect output :( I must be making some mistake, but couldn´t figure out.

You can do it like
Excel Formula: 
=LET(
all, $B$22:$E$31, name, CHOOSECOLS(all, 3), ph, CHOOSECOLS(all, 2),dept,CHOOSECOLS(all,4),
dptName, SORT(UNIQUE(CHOOSECOLS(all, 4,3)),,-1),
idDptName, LAMBDA(phs, IFERROR(MAP(INDEX(dptName,,2),INDEX(dptName,,1), LAMBDA(x,y, TEXTJOIN(", ", ,UNIQUE(FILTER(INDEX(all,,1), (dept=y)*(name=x)*(ph=phs)))))),"")),
idDptName1, idDptName(1), idDptName2, idDptName(2),
idDptNameCount, LAMBDA(phs, IFERROR(MAP(INDEX(dptName,,2),INDEX(dptName,,1), LAMBDA(x,y, TEXTJOIN(", ", ,ROWS(UNIQUE(FILTER(INDEX(all,,1),(dept=y)*(name=x)*(ph=phs))))))),"")),
idDptNameCount1, idDptNameCount(1), idDptNameCount2, idDptNameCount(2),
HSTACK(dptName,idDptNameCount1,idDptName1, idDptNameCount2,idDptName2))
